Cystometry is a test used to look for problems with the filling and emptying of the bladder. The bladder is part of the urinary tract. It’s a hollow muscular organ that relaxes and expands to store urine.
Cystometry measures the amount of urine in the bladder. That figure is compared with the bladder pressure and how full you think your bladder is. The result tells your healthcare provider about muscle function, mechanics, and nerve response of the bladder and urinary tract.
Normally, the bladder sends messages to the brain through nerve pathways when it needs emptying. The spinal cord then sends a message to the bladder to contract and start the reflex of urinating. Normally, you can override this reflex voluntarily to hold and control his or her urine.
Some conditions may interfere with the muscular function or nerve pathways between the bladder and the brain. These conditions may lead to loss of bladder control or urinary blockage. Cystometry may be used to find the source of such problems.
Cystometry may be recommended to check for problems of the bladder and urethra. Conditions that may cause problems of the bladder and urethra may include:
Problems in the urinary system can also be caused by aging, other illness, or injury.
Weak bladder muscles may result in not being able to empty your bladder completely. This is called urinary retention. Weak muscles of the urinary tract and pelvis can lead to loss of urine control. This is because the muscles cannot stay tight enough to hold urine in the bladder. Or the bladder does not have enough support from the pelvic muscles to stay in its proper position. Cystometry may be used to find the cause of symptoms like these.
There may be other reasons for your healthcare provider to recommend cystometry.
Some complications of cystometry may include:
Cystometry should not be done in someone with a urinary tract infection.
There may be other risks depending on your specific medical condition. Be sure to discuss any concerns with your healthcare provider before the procedure.
Straining with urination and certain medicines may affect the results of a cystometry procedure.
Based on your medical condition, your healthcare provider may ask for other specific preparation.
Cystometry may be done on an outpatient basis or during a hospital stay. Procedures may vary depending on your condition and your healthcare provider's practices.
Generally, cystometry follows this process:
There is no special type of care needed after cystometry. You may go back to your usual diet and activities unless your healthcare provider tells you otherwise.
You will be urged to drink extra fluids to dilute your urine and reduce urinary discomfort, such as burning.
You may feel some urinary discomfort, but it should lessen over time. Warm sitz baths or tub baths may help.
You may see blood in your urine after the procedure. The amount of blood will lessen over time.
Your healthcare provider may have you take an antibiotic to prevent a urinary tract infection.
Tell your healthcare provider to report any of the following:
You healthcare provider may give you other instructions after the procedure, depending on your situation.
